    1. The problem statement, all variables and given/known data

    Complete the following nuclear reactions

    Enter mass number, atomic number, and then symbol

    A) 232 92U--->4 2He + 228 /90 / _______________

    2. Relevant equations

    4 2He + 228 90U

    3. The attempt at a solution

    i got the mass number (228) and atomic number (90), but i could not figure out how to write the symbol.
    will anybody please help me?
    my guess of symbol was 4 2He + 228 90U but obviously it was wrong
